General hints for positioning
Avoid positioning the speakers in a corner or on the floor as
this will boost the bass tones too much. Placing the speakers
behind curtains, furniture, etc. will reduce the treble
response. The listener should always be able to see the
speakers.
Each room has different acoustic characteristics and the
positioning possibilities are often limited. You can find the
best position for your speakers by referring to the picture
above.
As a minimum we recommend 5 speakers (2 front, a center,
2 surround) for good surround sound. It is possible to
reproduce some kind of surround sound with fewer speakers.
This is done by redirecting the signals which are foreseen for
the missing speakers to the existing ones. See Menus on
how to set up the receiver correctly for the number and size
of the speakers used.
Positioning the front speakers
The front speakers should be placed right and left in front of
the listening position like usual stereo speakers.
Positioning the center speaker
The center speaker should be placed in the center between
the two front speakers, e. g. underneath or on top of the TV.
The best height for the center speaker is the height of the
listeners ears (while seated).
Positioning the surround speakers
The surround speakers should face each other and be in line
with, or slightly behind the listener.
Positioning the subwoofer
A subwoofer can be used to enhance the bass performance of
your system dramatically. The subwoofer can be positioned
anywhere in the room, because it is not possible to locate the
source of deep tones. Nevertheless, you should not place the
subwoofer in the middle of a room, since the bass could be
severely weakened. Do not place any object on the
subwoofer.
The relative volume of the speakers must be adjusted for
optimal surround sound. You should be at your usual listening
position when adjusting the speaker volume. See Receiver
menus on how to set up the receiver for the used speakers.
Ideally, the volume in the listening position should be the
same from all speakers.
1 Press POWER / STANDBY to switch on the receiver.
2 Press TEST TONE on the remote control.
y A test tone coming from the different speakers, except
the subwoofer, is heard.
3 Press +/- REAR on the remote control to
increase/decrease the volume of the actual speaker. The
best result is achieved when all speakers have equal
volume in the listening position.
4 Press TEST TONE on the remote control.
y The test tone stops.
Note: If you are not completely satisfied with the volume
settings, we recommend making minor adjustments to
them during surround sound playback.
If the receiver is used at very high power it can produce
distortions which may seriously damage your speakers. If
distortions occur, reduce the volume and the tone controls to
a level where the sound is acceptable again.
To avoid overheating of the set a safety circuit has
been built in. Therefore your set may disconnect under
extreme conditions. If this happens, switch the set off
and let it cool down before reusing it.
Connecting headphones to PHONES will switch off the
speakers. The receiver switches to STEREO and surround
sound will be reduced to a stereo signal which is reproducible
by standard headphones.
Disconnecting the headphones switches on the speakers
again. If you wish to enjoy surround sound again, switch the
receiver back to surround sound.
Clean the receiver with a soft,
slightly dampened, lint-free cloth. Do
not use any cleaning agents as they
may have a corrosive effect.
Do not expose the receiver to
humidity, rain, sand or excessive heat
(caused by heating equipment or
direct sunlight).
